Didn't work as of this review, but fixed it by replacing the removeButton variable with the following selector.

const removeButton = document.querySelector('[d="M11 17H9V8h2v9zm4-9h-2v9h2V8zm4-4v1h-1v16H6V5H5V4h4V3h6v1h4zm-2 1H7v15h10V5z"]').closest('[role="menuitem"]');

It is selecting the rubbish bin SVG path and searching the parent nodes up to the menu item.

The rest of the scripts works fine, I just have to go slow. If the pop up in the lower left corner says "sorry, something went wrong" the video was not removed. Now to clear 1000+ videos from a PocketTube playlist!

added a lock variable to prevent deletions until the pop up notifying the outcome appears.
